I am just building my first computer (going to instal linux, probably Ubuntu). I have been a Mac boy for the last four years so I am feeling somewhat confused.

I am thinking about getting this ASUS P8H67-M LE B3 Intel H67 Motherboard for $99 CAD.

According to the specs it has these display ports:

  • VGA Ports: 1
  • DVI Ports: 1
  • HDMI Ports: 1

Here are my questions:

  1. Since the computer has 3 ports for displays does that mean that I can plug in 3 displays? Will they all work at the same time? Will they mirror each other?
  2. If I can only use one display at the same time AND I buy a video card with one additional vga output. Will This allow me to use two screens?

  1. The H67 supports 2 outputs: HDMI, and DVI-I. The VGA is a peel-out from the DVI-I and does not function independently.

  2. Yes, depending on the OS.

How do you know this? Do you know this from reading the spec or do you just know. I want to avoid asking the same question again. – sixtyfootersdude May 4 '11 at 12:03
    
It's listed in the product brief as "Dual Independent Display", and VGA is not listed anywhere meaning that it must be a peel-out. intel.com/products/desktop/chipsets/ec-h67/h67-overview.htm – Ignacio Vazquez-Abrams May 4 '11 at 12:08
  1. According to the chipset specs, you can use up to two monitors with that motherboard using only the integrated ports. If you use all 3, I assume that one of them won't work, due to chipset limitations. If you use 2 displays, they, according to the specs, will not mirror unless they are set to, and will all work at the same time.

  2. As for adding a video card with a vga output, on some boards/chipsets this will work and on some it will not. Some choose to disable the onboard video when a pcie/pci card is attached. YMMV. Considering that it's a new board, I'd say it'll most likely work.

Where in the specs do you see that? – sixtyfootersdude May 4 '11 at 12:08
    
If you're talking about the chipset specs, I found them at intel.com/products/desktop/chipsets/ec-h67/h67-overview.htm . It's under the "Support for HDMI, etc" section. – Eli May 4 '11 at 15:15
